How to use std::atomic efficiently http://stackoverflow.com/questions/8749038/how-to-use-stdatomic-efficiently One practice I used is we have a buffer and I want to CAS on some bytes so what I did was uint8_t buf .... auto ptr reinterpret_cast.. pointer that reference to the location buf index Is the CAS on a single byte significantly slower than CAS on a machine.. Is the CAS on a single byte significantly slower than CAS on a machine word so that I should avoid using it My code will..
